• Description

• Fairview Microwave carries a broad selection of fixed attenuators with a wide range of attenuation levels, frequency ranges, and power

• dissipation ranges. Also known as RF pads, RF microwave attenuators lower the amplitude of a signal (or attenuate) a known amount. These

• attenuator pads can be used in a wide variety of applications including reducing a signal level to protect measurement equipment or other

• circuitry, extending the range of power meters and amplifiers, and impedance matching circuits by reducing the VSWR seen by adjacent

• components. RF attenuators can prevent signal overload in amplifiers, receivers and detectors, adjusting the signal level to a range that is

• optimal.

• Few RF components are as commonly used as fixed coaxial attenuators, and Fairview Microwave carries one of the largest in-stock varieties

• and ships them same day. The SA4S252-20 is a 20 dB Fixed Attenuator that operates from DC to 4 GHz and is rated to 25 Watts. The versatile

• coaxial package uses SMA male to SMA female connectors. The Black Anodized Aluminum Heatsink body allows for efficient heat dissipation

• under high power usage conditions.
